Getting ready to close pool for the winter. Any advice would be great. Thanks so much for all your help!

Hey there Jim, welcome back
Are you still using the Nature2 mineral cartridges, and trichlor tabs? We do NOT recommend adding metals to the pool and that's whats in that Nature2.
Calcium is high- do you have high calcium in your fill water? Have you been using Cal-Hypo? You can lower this by doing some water replacement assuming your fill water isn't also high? You are at a risk for scaling to develop on your walls because your pH is also on the higher end. Try to lower it to the 7.2-7.4 range while your calcium is high as that will help prevent the scale.
As you lower your pH with Muriatic Acid (MA) it will also bring your TA down some. That's a side benefit as it will help keep your pH swing up limited some.
Add a little CYA to get to at least 30ppm if you're in full sun all day. Refer to this: Pool School - Chlorine / CYA Chart
Water is crystal clear Not using pucks anymore. i am using vision crg-25 cartridges. I had pool company open my pool and they put a new cartridge in. btw, What's the best place to buy them? I am testing my water often so far and levels are looking better and better the cleaner the pool is. thanks for all your help.
Ok, You have to dumb it down for me. I did not install my pool so I'm just learning about pool water chemistry and how to handle the problems that come with it. (just got hip to you guys last year and thanks for that) Are you recommending that I uninstall the nature 2? because obviously it's hardlined into my pool plumbing. Not using pucks like the pool co. was recommending anymore. all My levels are all great now that I understand the relationship between CYA and chlorine.In reality, the best place to by them, is nowhere. You really should not be using any form of solid chlorine. And adding minerals is just asking for trouble. All you need is some CYA and chlorine. And a good test kit.
I have been using the TF-100 test kit since june 2015. This site has changed my perspective completely on pool ownership, water chemistry and basic pool maintenance. sadly has given me a very bad taste in my mouth for the pool company I used to install my pool.If you understand the CYA/FC thing then that's more then 1/2 the battle. I'm just concerned with the metals (usually copper) that the Nature 2 system put into the water. I would recommend not refilling it if it's empty. Other parts of the Nature 2 system use solid form chlorine that can cause your CYA to rise and reach levels where it becomes necessary to drain water to correct.
I may have missed it, but what test kit are you using?
